نویسندگان

چکیده

This letter presents a passivity-based inverse dynamics (ID) controller using global energy tank. The proposed control approach allows us to achieve safe multi-contact scenario on torque controlled humanoid robot. is primarily task space ID quadratic programming (QP) which efficiently computes the reference satisfying non-hierarchical set of tasks. Our work extends this by adding tank modulating gains, with power regulation, ensure passivity system. method combines benefits controller, an optimal without joint feedback, and system, robust model uncertainties external disturbances. robustness our framework demonstrated in Gazebo simulations, where robot TALOS achieves 20 cm step walk, objectives Cartesian configuration spaces, control. implementation open-source.

Exploiting Friction in Torque Controlled Humanoid Robots

A common architecture for torque controlled humanoid robots consists in two nested loops. The outer loop generates desired joint/motor torques, and the inner loop stabilises these desired values. In doing so, the inner loop usually compensates for joint friction phenomena, thus removing their inherent stabilising property that may be also beneficial for high level control objectives. This paper...

Momentum control with hierarchical inverse dynamics on a torque-controlled humanoid

Hierarchical inverse dynamics based on cascades of quadratic programs have been proposed for the control of legged robots. They have important benefits but to the best of our knowledge have never been implemented on a torque controlled humanoid where model inaccuracies, sensor noise and real-time computation requirements can be problematic. Using a reformulation of existing algorithms, we propo...

Experiments with Hierarchical Inverse Dynamics Controllers on a Torque Controlled Humanoid

We expect autonomous legged robots to perform complex tasks in persistent interaction with an uncertain and changing environment (e.g. in a disaster relief scenario). Therefore, we need to design algorithms that can generate precise but compliant motions while optimizing the interactions with the environment. In this context, torque control algorithms often offer high performance for motion con...

Balancing and Walking Control for a Torque-controlled Humanoid Robot

Samsung Electronics Co., Ltd. has been developing humanoid robots for years. Roboray, the latest developed humanoid robot in Fig. 1, has many different characteristics from the previous robots, e.g. Mahru series [1]. The main difference is that Roboray can be torque-controlled with torque sensors at all joints in the lower limbs. There exist some released biped robots which have torque/force co...

Inverse Kinematics for Humanoid Robots

Real-time control of the endeffector of a humanoid robot in external coordinates requires computationally efficient solutions of the inverse kinematics problem. In this context, this paper investigates methods of resolved motion rate control (RMRC) that employ optimization criteria to resolve kinematic redundancies. In particular we focus on two established techniques, the pseudo inverse with e...
